A recently granted patent (Publication Number: US11884290B2) discloses a vehicle test system designed for automated driving operations. The system includes a vehicle speed control device that operates the accelerator and brake pedals based on a vehicle speed command. The vehicle speed command generation device comprises a shift processing unit and a correction processing unit. The shift processing unit generates different versions of the vehicle speed command by delaying an original command by specific time intervals. The correction processing unit then corrects the reference command using these delayed versions to generate the final vehicle speed command for the control device.

Furthermore, the patent details a method for generating vehicle speed commands in a test system. This method involves receiving an original vehicle speed command, generating reference, first-out, and delayed versions of the command by applying predetermined delay times, and then correcting the reference command using the other versions to create the final vehicle speed command. The system also includes components such as an original vehicle speed command generation device and a measuring device to assess the vehicle's performance, operating synchronously with the delayed commands. Overall, the patented technology aims to enhance the precision and efficiency of vehicle testing processes by optimizing the generation of speed commands for automated driving operations.
